I need a sanity check
(OP)
Say you've got a fixture on a wing that undergoes a 10g vertical maneuver going through the CG of the fixture, and on the end of the fixture is an object "d" on a linkage distance "a" from the fixture. If you need to use torque to resist that loading scenario the torque required would just be T = 10*Md*g*a, right?





RE: I need a sanity check
Does object d can rotate around pin on the plane of the drawing?
If so, is that rotation what you try stopping with a moment applied on the pin?

RE: I need a sanity check
Yes, object d can rotate around the pin. Lets say you had a motor directly on the pin that reacted to the G forces to keep object d in it's orientation.
RE: I need a sanity check
I might be misunderstanding the problem but the direction of the forces drawn result in a couple acting around the pin d
if you take moment about pin d then the resisting moment in my mind should be equal to (Md)g*a + 10*b
